A traveler's favorite that owners keep in their bag
Owners call the Anker 737 their go-to battery, and several have used theirs for two years or more. It can charge a laptop at up to 140W, holds enough for about five phone charges, and stays under airline limits. The trade-offs are weight (about 630 g) and some reports of units failing within a year. The warranty is the safety net.

Tips from owners
- Use a 100W+ USB-C charger to refill it quickly.
